How do I feed my nocturnal fish?

Fish who are nocturnal (active at night, such as many catfish) may only eat when the lights are out. They tend to find a hiding spot when there is light and they are able to see movement. This means you may see very little of a nocturnal fish during the daylight hours, or when the aquarium is lit. These fish may only eat at night, and are best fed in the evening.
